HASP-MOUNTING.

Specification of Letters Patent.

Patented June 26, 1917.

To all whom it may concern:

Be it known that we, WILLIAM C. MARTI- NEAU and CLARENCE R. MARTINEAU,citizens residing at Albany, county of Albany, and State of New York,have invented certain new and useful Improvements in Hasp-Mountings, ofwhich the following is a specification.

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.

Our invention relates to hasp-mountings locking devices, and isparticularly adapted for the locking dedoors of railway cars for variouskinds of vices of the sliding and the like.

As an example of one form of locking device to which the invention isapplicable, reference may be had to U. S. Letters Patent No. 1,149,205,granted to us August 10, 1915.

The principal object of our invention is to provide a strong and durablemounting for the hasp of a locking device, to prevent the escape of thehasp from its pivot, and to reinforce the pivot to better resist theendthrust of the hasp.

Other objects will appear in connection with the following description.

Figure 1 of the drawings is a plan view of a hasp-mounting embodying ourinvention.

Fig. 2 is a central vertical longitudinal section of the same taken onthe broken line 2-2 in Fig. 1.

Fig. 3 is a side view of the staple-form keeper.

Referring to the drawings wherein the invention is shown in preferredform, 1, is a hasp having at its inner end a pivot-eye, 2. The outer endof the hasp may be provided with the usual aperture, 3, for the bolt orstaple of the complementary member of the locking device, not shown.

The hasp, 1, is pivotally mounted upon a supporting-plate, 4, which isprovided with bolt-apertures, 5, whereby the plate can be attached to asliding door or the like.

The plate 4, is preferably made of malleable cast-iron, and has castintegral therewith two tubular bosses, 67, arranged longitudinally ofthe plate.

The boss, 6, passes through the pivot-eye,

' 2, of the hasp, and forms the pivot for the hasp.

To prevent the escape of the hasp from its pivot, and to reinforce itspivotal connection with the plate, 4, we employ a keeper, 8, in the formof a staple, one leg 9, of the keeper being inserted through the tubularboss, 6, and its other leg 10, inserted through the tubular boss, 7,with the body of the keeper extending over part of the pivot-eye 2, ofthe hasp.

The ends of the legs, 9 and 10, of the keeper are upset or riveted uponthe under side of the supporting-plate, 4, as shown at 11, in Fig. 2,whereby the keeper is rigidly secured to the plate. 1

The pivot-eye, 2, of the hasp is formed with suflicient lost-motion topermit the nelghboring end of the hasp to abut against the boss 7, whichis outside of the eye of the hasp.

The end-thrust of the hasp in the direction of the boss, 7, is thusresisted by both bosses, 6 and 7, as will be seen from Fig. 2.

By having one leg of the staple-form keeper, 8, inserted through theboss, 6, and its other leg secured in rigid relationship to the plate,4, at a point outside of the pivot-eye, 2, of the hasp, the keeper notonly serves to prevent the escape of the hasp from its pivotalconnection, but reinforces the pivotal connection formed by the boss, 6,and serves to transmit part of the stress upon the pivot-boss 6, throughthe leg, 10, of the keeper to the plate, 4, at a point more or lessdistant from the pivotboss, 6.

By means of the boss, 7, the plate, 4, is reinforced at its point ofconnection with the leg, 10, of the keeper, and the stress transmittedthrough the leg, 10, is better distributed to the plate, 4.

The eye-portion of the hasp is preferably made of such cross-sectionalform that it engages the respective bosses, 6 and 7, at pointsimmediately adjacent to the surface of the plate, 4.

The body, 8, of the keeper is necessarily located at a certain distancefrom the surface of the plate, 4, sufiicient to permit the hasp to beswung freely upon the keeper in all directions.

We find it desirable to make the dimen sions of the eye of the hasp atth inner end of the hasp, such that, when the hasp is in lockedposition, said eye-portion will have practically only the same clearancewith respect to the body, 8, of the keeper, as it has in its swingingmovements This result we are able to accomplish, while preventing theeye-portion of the hasp from engaging the except at points closely basesand the surface of the plate, providing the hasp with an annular flange,12, extending around its eye-portion whereby the height of theeyeportion is substan,- tially equal to the horizontal cross-sectionaldimension of the eye-portion, as-shown in Fig; 2.

In order to confine the thrust to the bodyadjacent to their portion onlyof the hasp and thus to the base portion only of the bosses, 6 and 7 orsimilar devices whereby the hasp is pivotally mounted, the outer portionof the flange, 12, is so formed as to taper or retreat from theedge-portions of the hasp bordering the pivot-eye, 2, and bordering theneighboring,

end of the hasp.

WVhat we claim as new and desire to sec-o cure by Letters Patent is' 1.In a hasp-mounting and in combination, a hasp provided with apivot-eye;a supporting-plate having an integral tubular pivot-boss passing throughthe-eye of the hasp; and a keeper in the form of a staple having one legpassing through the tubular boss and secured to the plate, and its otherleg secured to the plate outside of the eye of the hasp.

2. In a hasp-mounting anduin combination, a hasp provided with apivot-eye; a

Copies of this patent may be obtained for bosses 6 and 7,

neighboringend of the hasp to abut against the other boss; and a keeperhaving two legs inserted through the respective tubular bosses andsecured rigidlyto said plate;

4h In a hasp mounting and in combination, a hasp provided with apivot-eye; a pivot passing throughthe pivot-eyeof the hasp; and a keeperoverhangingthe pivoteye of the hasp, the hasp being adapted to swingfreely upon the pivot andthe keeper,-

and having adjacent to its eye an outwardly extending flange whereby theclearance of.

the eye-portion of the hasp with reference to the keeper when thehasp isin locked position is substantially the same as its clearance in theswinging, movementsof the hasp, the outer portion of said flangeretreating from the edge-portions of the hasp, whereby end-thrust'isconfined .to the body-portion only of the hasp.

In testimony whereof, we have hereunto set our hands this 21st dayofSeptember WILLIAM C. MARTINEAU. CLARENCE R. MARTINEAII.
